Question

Which pf the following has a graph that is a straight line?

Answer 1

Answer: Third option.

Explanation:

By definition, the equation of the line in slope-intercept form is:

`y=mx+b`

Where: m is the slope of the line and b is the y-intercept.

As you can see in the options shown in the image attached, the only equation that has the form of the equation of the line in slope-intercept form is the Equation 3, which is:

`y=12x+17`

Where:

`m=12\\b=17`

Therefore, the graph of the Equation 3 is a straight line.
